Since the keys of our keys were broken (they had replaced), but the technique was still fully functional, I have experienced the Opel dealer that a new key costs about 200 euros. Thus I have decided this case to buy. The delivery was very quick. The first time you view a lot already in that some parts like the button to pull down the beard, and the mechanics are in contrast to the original plastic instead metal. Since it but appeared very valuable, I built the board, the battery and the beard. The worked without any problems. During mating of the housing was then but realized that it was not for eternity. several times the whole thing fell apart again. Well, so I've stuck together with plastic glue the two housing parts. Thus, it held then. Until he flew me when getting out of the car about half a meter to the asphalt and all the items in the dark night spread out. Of course I have not recovered all small parts and thus everything again built back in the old housing. A BUY recommendation I can not really give so.
